| 摘 要： | 本文提出了一种基于局部能量的自适应图像融合方法。首先对原始图像进行小波分解,得到低频和高频子图像。然后分别计算高频子图像的局部能量,再根据不同图像的相应局部能量,计算局部能量熵,并根据值局部能量熵构造融合系数,从而实现图像融合。最后通过小波反变换,得到完整的融合。实验结果表明该方法有较好的融合效果。

| Abstract: | In this paper,an adaptive image fusion algorithm based on local energy is proposed.Firstly,the wavelet transform is used to perform a multiscale decomposition each image.Secondly,it calculated the local energy and the local energy entropy.Finally,it chose the fusion pixel based on the weighting coefficients,which is calculated by local energy entropy.The result image is generated by reverse wavelet transform.The experiment result appears the proposed method makes obviously effects. |
